root-HANDL Specification of letters Patent.

Patented Aug. 8, 191d.

Application filed February 2, 1915. Serial No. 5,698.

To all whom it may concern.-

Be it known that I, FREDRIOK W. Gnoss- MANN, a citizen of the United States, residing at Mount Vernon, in the county of Westchester and State of New York, have invented certain new and useful Improvements in Tool-Handles, of which the following is a specification.

This invention not only aims to secure the tool to its handle, but has for its object to reinforce the handle, the reinforcement being a part of the securing means.

A further purpose of the invention is the provision of a handle of novel formation ception of the rod by means of which such handle is reinforced and the tool held in place thereon.

A further purpose of the invention is to utilize the connecting means for preventing separation of the sections comprising the handle, the washer mounted upon the rod being formed with a recurved portion to engage the sections of the handle adjacent the opening therein through which the rod passes.

With these and other objects in view,

which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly claimed.

In the accompanying drawings has been illustrated a simple and preferred form of the invention, it being, however, understood ,that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modieo fications within the scope of the invention as claimed may be resorted to when desired. Referring to the drawings :Figure 1 is a view in elevation of one section of the handle having the tool held in place thereon by means embodying'the invention, a portion of the tool being broken away to show i the relation of the elements. Fig. 2 is a sectional detail on the line 22 of Fig. L

Fig. 3 is a-perspective view of the tool and no the outer end of the handle showing the securing means. Fig. L is a horizontal section on the line 44 of Fig. 1. Fig. 5 is a section on the line 5-5 of Fig.1 looking upward. Fig. 6 is a detail perspective view at of the connecting and reinforcing rod. Corresponding and like parts are referred having a longitudinal opening for the reto in the following description and indicated in all the views of the drawings by the same reference characters.

For the sake ofillustrating the application of the invention the tool shown consists of a hammer which is typical of the variety provided with an eye for receiving the handle. The eye of the tool 1 is laterally flared at its outer end as indicated most clearly in Fig. 2 the purpose being to admit of the outer end of the handle being spread by the wedge so as to prevent the tool becoming loose or leaving the handle. The eye 2 of the tool is elongated in the length of the tool and is provided at opposite points at its outer end with recesses 3 for receiving projectionsat the outer end of the wedge.

These recesses 3 may be formed in any manner either at the time of constructing the tool or subsequently by a milling operation. In the preferable construction the recesses 3 are subsequently formed by means of a milling tool and this operation admits of adapting the invention to tools already constructed.

The handle 4 is preferably constructed of wood such as hickory. The preferred method employed in constructing'the handle consists in providing two boards, blocks or like members and running the same through a machine whereby a plurality of corresponding grooves and tongues are formed in the meeting faces. operation the boards, blocks or the like are placed together and secured by glue or like cementitious material applied to the meeting faces, pressure being applied to clamp the parts and hold them secure until the glue or other cementing material sets. The composite board, block or the like thus formed is cut up into strips or blanks which constitute the individual handles, such blanks being finished in any manner commonly resorted to for forming tool handles. The

Subsequently to this handle thus formed comprises two sections ing. The opening 7 at theinner end of the handle is enlarged, as indicated at 9 to receive a plug 10 and' the fastening means applied to the outer end of the rod 8 such as a washer 11 and nut 12. The opening 7 wedge 13 is formed at the opposite end of the rod 8 and this wedge at its base or outer end is formed with projections 15 which snugly fit within the recesses 3. While the rod 8 and wedge 13 may be formed in any manner it is preferred to construct the same of steel by drop forging, thereby providing a connection which strengthens and reinforces the handle and insures durability and a substantial structure.

The Washer 11 is preferably of cup-shape and its rim is formed with a recurved edge 16 which is adapted to engage and interlock with the adjacent end of the handle so asto assist materially in holding the parts or sec-. .tions from separating. The washer 11 sustains the end thrust of the connecting rod 8 incident to tightening the nut 12. The enlarged portion 9 of the opening 7 is contracted at its inner end to receive the cup portion of the washer 11 and to form a shoulder for receiving the recurved edge portion 16 of the rim. The recurved edge por tion 16 becomes embedded in this shoulder, as indicated most clearly in Fig. 1, thereby forming an interlockingjoint to prevent separation of the parts or sections comprising the handle even though the cementing material should loosen by reason of dampness or from other cause.

In carrying out the invention the tool is slipped upon the outer end of the handle after which the connecting rod 8 is passed through the opening 7. The wedge 13 is forced into the enlarged end of the opening 7 preferably by tapping the wedge with a hammer or like tool. The washer 11 is placed upon the threaded end of the rod 8 after which the nut 12 is fitted to the threaded end 14.- and screwed up tight. The opening 9 is closed by means of the plug 10' which is forced therein. When the parts are properly assembled the outer end of the wedge 13 comes flush with the outer side of the tool, thereby leaving no projecting parts and the projections 15 at opposite ends of the wedge 13 enter the recesses 3 thereby preventing the tool from leaving the handle. Should the outer end of the handle shrink or the joint tend to become loose the plug 10 may be removed and the nut 12 given one or more turns, thereby forcing the handle and the wedge 13 in opposite directions with the result that the outer end of the handle is spread so as to take up any shrinkage and insure the formation of a tight joint. The rod 8 in addition to serving as means for holding the wedge 13 and handle in proper position with reference to each other and to the tool, also serves to reinforce and strengthen the handle. While the tool is held upon the handle against possible displacement it is observed'that the connection is such as to admit of the tool being readily removed from the handle when desired, such result being accomplished by removing the nut 12 and tapping the rod 8 to loosen the wedge 13 after which the rod may be readily withdrawn and the tool disconnected from the handle.

Having thus described the invention, what is claimed as new is 1. A tool handle divided longitudinally to form co-acting sections, one end of the handle seated in the eye of the tool, a

ing means and hold the section-holding means in place.

2. A tool having an outwardly-flared eye and formed with opposed recesses at the outer end of the eye, a handle consisting of mating longitudinal sections having one end filling the eye in the tool and having a longitudinal opening coterminous with the handle, said opening being enlarged at its opposite ends, a rod inserted through said opening and threaded at one end and formed at its opposite end with a wedge and projections at opposite ends of the wedge,

said wedge fitting in the enlarged part of the opening at the outer end of the handle and expanding said end of the handle against the flared walls of the eye in the.

tool and the projections extending beyond the sides of the handle and fitting in the recesses at the end of theeye, a washer mounted upon the threaded end of the rod and interlocking with the handle sections to prevent spreading of the same, a nut engaging the threaded end' of the rod and bearingagainst the washer to serve as tightening and holding means for the parts, said Washer and nut occupying the enlarged part of .the opening at the inner end of the handle, and a plug fitted in the, enlarged end of the opening to conceal the nut and washer.

3. A tool having an eye, a handle inserted in said eye and consisting of mating members provided with inter-engaging longitudinal grooves andribs on their opposed faces and having central longitudinal grooves whereby to form an opening extending entirely through the handle, a, rod in- In testimony whereof I affix my signature serted through said central longitudinal in presence of two Witnesses. opening, means at one end of said rod to spread the handle in the eye of the tool, and FREDRIGK GROSSMANN' means at the opposite end of the rod to hold Witnesses: the handle in place and prevent the sections JOSEPH C.
